SPECIFICATION forming part of Letters Patent No.- 532,688, dated January 15, 1895.

Application filed ml 19, 1894.. Serial No. 504,191. (No model.)

' Machine, of Which the following is a full, clear,

and exact description.

The invention relates to machines used for wrapping newspapers and other publications, for mailing. I

The object of the invention is to provide a new and improved paper wrapping machine, which is comparatively simple and durable in construction and very effective and automatic in operation.

The invention consists principally of an in termittently revolving core on which the paper and wrapper'are wound, and apresser cylinder mounted to rotate in conjunction with the said core, and arranged to swing toward and from the said core.

The invention also consists of certain parts and details and combinations of the same, as

will be hereinafter described and then pointed out in the claims. I

Reference is to be had to the accompanying drawings, forming a part of this specification,

.in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a rear elevation of the same.

Fig. 3 is an enlarged cross section of the same on the line 33'of Fig.2. Fig. 4 isa similar B by a suitable clutch mechanism B under the control of the operator. On the shaft B is also secured a fly-wheel B and a pinion B in mesh with a large gear wheel 0 secured on one end of the cam shaft 0, mounted to turn in suitable bearings in the main frame A, and extendinglongitudinally, similar to rotate the pressure cylinder D which operates in conjunction with the core E having an intermittent rotary motion derived from the said presser cylinder D, which latter is mounted to swing toward and from the said core E, as hereinafter more fully described.

The paper and wrapper are fed between the core E and the presser cylinderDfrom a feed table F, at the time the said cylinder D is close, to the core E, so that the cylinder D and core Erevolve in unison and cause the paper and wrapper to be pulled forward between the core and the cylinder to be finally wound on the core, as hereinafter more fully described.

In order to impart a rotary motion to the presser cylinder D from the cam shaft 0, I provide a'gear wheel 0 adapted to be secured on the said shaft Gland in mesh with a gear wheel D fastened on the shaft D on which the presser cylinder D is secured. In order to change the speed of the cylinderD relative to the speed of the shaft 0, I may disconnect the gear wheel C from the shaft 0 to move it out of mesh with the gear wheel D and then fasten a larger gear wheel 0 on the shaft 0 and in mesh with a smaller gear wheel D on the shaft D. In either case the presser cylinder D will be rotated from the shaft 0 by the corresponding set of gear wheels C D or C D I The shaft D carrying the presser cylinder D is journaled in a frame D mounted to swing and fulcrumed onthe shaft 0, so that a swinging motion, given to theframe D in the manner hereinaftermore fully described, causes the said presser cylinder D. to swing toward. or. from the core E, without moving the corresponding gear wheels 0 D or C D out of mesh.'

the shaft B. This cam shaft 0 is adapted to On the shaft D is secured a large gear.

at the time the presser cylinder D swings toward the core E,'so that the rotary motion imparted to the presser cylinder D is transmitted to the core E during the time the paper and wrapper are pulled between the core E and cylinder D, as previouslymentioned, and when the said cylinder D swings away from the core E, the gear wheel D moves out of mesh with the gear wheel E and the said core E stops rotating and remains stationary during the time the cylinder D is in an outer- 1j During this time the paper most position. and wrapper around the core E are pushed ofi from the latter, as hereinafter more fully described.

The wrapping paper G for forming the wrappers, unwinds from 'a roll of paper G 1 supported in the lower part of the mainframe I A, the paper then passing upward at the front of the machine over a roller G2 and over a roller G3 journaled in the upper end of the feed table F, the paper then passing down the inclined top surface of the said table to and between feed rollers F and F rotating together and journaled in suitable bearings in the feed table, in such a manner that their opposite surfaces are in a line with the top surface of the feed table F, as will be readily understood by reference to Fig.'5, the said feed roller F extending from underneath through a slot in the said table.

During the time the wrapping paper G passes over the upper part of the feed table means of the curvedguides, H, which partly encircle the core, as shown in Fig. 5. A grav ity foot F is pivoted on the lower end of the feed table F and adapted to swing so as to stand either at right angles to the feed table, as shown in Fig. 5, orto swing downward to be in alignment with the feed table. For this purpose the foot F is provided on its uhder side with an arm F (see Fig. 5) resting on the peripheral surface of camF 'fulc'rumed on the main frame A and provided with a tail F adapted to be engaged by an arm D projecting from the frame D? carrying the presser cylinder D, so that the'swinging of the frame D causes the arm D to imparta swinging motion to the tail F and its cam F so as to permit the foot- F to swing downward in alignment with the feed tableF,or to'cause the said foot F to swing upward intb a right angularposition'to the feed table F, to form a stop or abutment for the downwardly fed wrapper and newspaper. Thus, when the swinging roller, D,is swung outward, as shown in Fig. 5, the cam F is held in "position to maintain the foot F in itsraised position, so that it arrests the sheet descending on the table, F. On the otherhand, when thejroller, D, has been swung inward into contact with the core, E, (Fig. 4,) the cam swings backward, and allows the foot, F to fall into alignment withthe table, F, so as to form virtually a continuation or elongation of the latter. Itis to be understood, however, that the foot, F is only used when newspapers and wrappers are fed by hand, and not when automatic feedmechanism is employed. As the wrapper and newspaper pass between the cylinder D and the core E they are guided or turned upward so as to wind around the core E, by curved guides H partly encircling the core E, as plainly illustrated in Fig. 5.

The inner surface of eachguide II is concentric to the outer surface of the core E, sufficient space being left between the said outer surface of the core and the inner edge of the guide to correspond with the thickness of the paper and wrapper fed bewteen the core and cylinder. Each guide 11 is held transversely adjustable, and for this purpose is provided on its under side with a guideway H fitted to slide in suitable bearings A formed on a bracket of the main frame A. A screw H turning in the bearing A, screws in a lug H projecting downward from the guide H, so that by turning the said screw, the guide can be moved forward orbackward in its hearing A, so as to bring the guide in proper position relativeto the core E.

In order to permit the cylinder D tomovc close to the core E, I form the cylinder with annular grooves D in alignment with the guides I-I, so that the latter pass into the said grooves at the time the cylinder D moves close up to the core E, to press the wrapping paper and newspaper tightly onto the core to feed it forward into the space between theguides H and core E, so asto cause the papers to wind on the core E. At the time the wrapping paper, with the newspaper on top of it, has been passed between thefeed rollers F and F and the upper ed e of the newspaper is a suitable distance below the said feed rollers, then the lower part of thewrapping paper is detached from the paper G to formthe wrapper for thisindividual newspaper. In order to do this, a cutting knife I is provided, adapted to cut thewrapping paper ashort distance above the upper edge of the newspaper, the said knife moving toward the feed table, to cut the wrapping paper, over aknifeblock I, asplainly shown in Fig. 5. The cutting knife I is held on a swingingfframe I secured on a shaft 1 extending longitudinally and mounted to turn in suitable hearings in the sides of the main frame A. On one end of this shaft 1 is secured an arm 1 carrying a friction roller l traveling in the groove of a cam I secured on the cam shaft 0, as plainly shown'in Fig. 2, so that the rotary motion of the shaft O causes the cam 1 to impart a swinging motion to the arm 1 so as to rock the shaft 1 and consequently, the frame I carrying the cutting knife I, to move the latter at the proper time onto the wrappingpaper to cut the wrapper from the paper G. On this swinging frame l and below the cutting knife I, is journaled a pasting or guniming roller J adapted to apply the gum or paste to the wrapper near the upper edge. V This pasting or gumming roller J is adapted to travel over a paste table J made segmental, with the center at the shaft 1 the said roller being adapted to travel over this table J onto a supply roller J 5 mounted to turn in a pastebox J arranged at the forward end of the table J. A scraper J removes the surplus paste on the roller J the latter rotating in the said box J continually, its motion being derived from the main driving shaft B by providing the outer end of the shaft of the said roller with a pulley J 5 over which passes a belt J 6 also passing over a pulley J 7 fastened on the saidv main driving shaftB, as plainly shown in Figs. 2, 3 and 4. The cutting knife Icuts the paper at the time the paste roller J moves in contact with the upper edge of the paper a short distance above the upper edge of the newspaper. and wrapper pass between the presser cylinder D and core E to be wound on the latter, 'then the extra gummedlength of the wrap- E rotating in unison.

. The feed rollers F and F are geared together, and for this purpose the shaft F of the lower feed roller F carries a gear .wheel F in mesh with a gear wheel Fsecured on the shaft of the top roller F See Fig. 6. The shaft Flof the roller F. receives an intermittent rotary motion from the gear-wheel D2 of the shaft D ,and for this purpose I provide the said shaft F with a pinion K in mesh with an intermediate gear wheel K adapted to be engaged by the gear wheel D at the time the presser cylinder D swings toward the core E. Thisintermediate gearwheel K is journaled on an arm K fulcrumed loosely on the shaft F and pressed on, at its outer end, by aspring K as plainly shown in Figs. 3 and 4. The

. spring K is held on the feed table F and serves. to move the forward end of the said arm K downward to carrythe gear wheel K in such a position to be readily engaged by "the-advancing or forwardly swinging gear wheel D I In order to impart the necessary swinging motion to the presser cylinder D,,as previously mentioned, I provide two friction rollers L journaled on arms L fulcrumed at L on opposite sides of the main frame A, the

Thus, when the paper L to impart a swinging motion to the arms L, whereby the friction .rollers L press on the lower ends of the frame D to cause the latter to swing to move the cylinder D outward away from the core E.

s The lower end of the frame D is connected by links D with a flat spring D secured at its middle on a post'A forming part of the main frame A. The spring D serves to press the lower end of the frame D by the links D to hold the presser cylinderD normally atits innermost position close to the core E, so that when the presser cylinder D is swung outward by the action of the cams L on the inder D is moving away from the core E and the latter comes to a standstill after the newspaper and wrapper are wound around the said core, as previously described, and the ends of the wrapper are gummed together, then a pushing mechanism N takes hold of one end of the said wrapped paper to push it off the core E to move the said paper between two rollers O and 0, so as to. flatten the cylindrical form of the wrapped paper. This pushing device N is constructed as follows: A ring N surrounds the core E and is held on two longitudinally extending rods N attached. to a crosshead N fitted to slide loosely on thefixed shaft E carrying the core E. The crosshead N isprovided with the trunnions N engaged by the slotted end P of a lever P, fulcrumed at P on a bracket A forming part of the main frame A. .The lower end of this lever P is pivotally connected by a link P with the lower end of a lever P fulcrumed at P on the said bracket A the upper end of the said lever P carrying a pin engaged by a cam groove on a cam P7 secured on the cam shaft 0. The cam P holds the ring N by the intermediate mechanism described, on one end of the core E during the time the wrapper and paperis wound on the core E, and when the latter is at a standstill, as previously described, then the said cam P on the further rotation of the camshaft 0 causes the lever P to swing core during the next operation of coiling the I paper and wrapper around the core E.

The rollers O and O operate in conjunction with each other and for this purpose their shafts O and 0 respectively are provided with gear wheels 0 and 0 respectively, in

mesh with each other, as plainly shown in Fig. 1. The outer end of the shaft 0 carries a bevel pinion 0 in mesh with a bevel gear wheel 0 secured on the main driving shaft B so that the rotary motion of the latter transmits a like motion to the roller 0' and the latter, by the gear wheels 0 and O rotates the roller 0. The lower roller 0' has its shaft 0 journaled in stationar'ybearings, while the bearings for the upper roller 0 are fitted to slide vertically in suitable guideways A forming part of the main frame A. Springs 0 press on the said hearings to hold the roller 0 firmly in contact with the paper passed between the rollers Oand 0' so as to properly flatten the same.

The operation is as follows: Wheat-he main.

downward over the feed table F, and at this time a newspaper or other publication to be wrapped is fed onto the lowerend of this wrapping paper on the feed table F, so that both the wrapping paper and the newspaper :pass between the cylinder D and the core E which now rotate together so as to pullthe two papers forward and to causethepapers to coil around the core E owing to the action of the guides H encircling part of the core E. Atthe time the two papers are passed betweenthe cylinder D and core E and the upper endof the newspaper has passed the lowerend of the feed table F, then the cutting mechanism I cuts off the wrapper from the paper-G, andat the same time, the gumming roller J applies paste or gum onto the free end of the wrapper so that on the further drawingin of the newspaper and wrapper the gummedend of the wrapper will overlap theother end, thus fastening the wrapper around the paper. As

soon as this has been done, the presser cylin-;

der D is caused toswing outward by the action of the cams L on the arms L, as previously described, whereby the gear wheels D and E are thrown out of mesh and likewise the gearing connected with the rollers F and F so that the core E, aswellas the said rollers F, F remain at a standstill for the time being. N is actuated from thecam P so that the ring N slides forward onthe core Etopush the wrapped newspaper off the core E and be+ tween the rollers O and 0, so that the wrapped paper is flattened, it being understood that the said rollers O and 0' completely draw the wrapped paper between them, asthe rollers have a continuous rotary motion derivcdfrom the main driving shaft B. As soon as the pushing device Nhas returned to itsnormal position the pressure cylinder D'swingsiinward toward the core E, so that thelatteris At this time the pushing device again rotated and a like motion is given to the rollers F and F to againfeed the paper G downwardover the feed table F to form a new wrapper below the said rollers F and F to receive the newspaper to be wrapped. The above described operation is then repeated. Pasters bearing the address may be attached to the paper G previous to forming the wrappers, or the said pastors may be attached to the wrappers after the finished product leaves the rollers O and 0'.

Having thus fully described my invention, I claimas new anddesire to secure by Letters Patent- 1. In a paper wrapping machine, the combination with a cylindrical rotatable core, of
